MAKO robotic assisted total hip replacement (THR) for patients with fused hips

Abstract

Background Previous articles about MAKO robotic‐assisted total hip replacement (THR) were mainly in patients with comparatively normal anatomy. Methods From July 2020 to June 2021, we performed MAKO robotic‐assisted THR in three hip‐fused patients. We assessed the accuracy of prostheses implantation, collected clinical data, and discussed the value of this technique in this kind of patients. Result All three patients achieved good leg length and prostheses position. A patient got femoral artery injury during the surgery. Moreover, she developed a thrombus. All three patients got acceptable Visual Analogue Scale scores and function recovery 6 months later. Conclusion MAKO robotic‐assisted THR achieved excellent prosthesis position in hip fused patients. More cases are needed to confirm this advantage. The function recovery was acceptable. Caution should be paid to protect the surrounding abnormal arteries, especially in a limited surgical field.

Accuracy of a Three-Dimensional (3D)-Printed Patient-Specific (PS) Femoral Osteotomy Guide: A Computed Tomography (CT) Study

“…Surgeons use either free-hand osteotomy [ 18 ], robotic arm [ 19 ] or Three-Dimensional (3D)-printed Patient-Specific Instruments (PSI) [ 20 , 21 ] to execute the osteotomy. Free-hand femoral neck osteotomy is typically performed by surgeons using their experience and finger measurements, potentially inducing uncertainty about the reproducibility of the planned femoral neck osteotomy level [ 18 ].…”
